MUSIC-LEAF TURNER.

Application filed July 29, 1922.

To all lwhom t may concern:

Be it known that I, Torvo PELToLA, a citizen of the United States,residing at Marquette, in the county of Marquette and State of Michigan,have invented certain new and useful Improvements in Music-Leaf Turners,of which the following is a specification.

This invention relates to music leaf turners, and has for one of itsobjects to improve the construction and increase the eiiiciency andutility of devices of this character.

VAnother object of the invention is to provide a device of thischaracter which may be supported by a foldable standard of the usualconstruction, or upon the usual music rack of a piano, organ, or likeinstrument, without material structural change.

With these and other objects in view the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claim, and in the drawingsillustrative of the preferred embodiment of the inventionz- Y Figure 1is an elevation of the improved device supported by a conventionalfoldable music stand, for use by individual performers in a band ororchestra.

Fig. 2 is a side elevation of the upper part of thestructure shown inFig. 1.

F ig.- 3 is a rear elevation of the upper portion of the structure shownin Figs. 1 and 2, illustrating the manner of operating the leaf turningarms.

Figs. 4 and 5 are enlarged detail views of the adjustable magnet devicefor seizing the leaves for turning.

Fig. 6 is a view similar to the upper part of Fig. 1, illustrating themanner of supportingthe backs of the music sheets and the intermediateleaves upon thesupporting structure.

Fig. 7 is a section on the line 7-7 of Fig. 6.

Fig. 8 is an enlarged detail of the turning rod mechanism.

Fig. 9 is an end View of the parts shown in Fig. 8.

Fig. 10 is a view, on a reduced scale, ofa music leaf, showing itarranged for use on the improved device.

Fig. 11 is an end view of Fig. lO.

Fig. 12 is a view on a reduced scale, of a conventional sheet of music,including the serial No. 578,431.

back, the front or cover, and the intermediate loose leaf.

Fig. 13 is a view, on a reduced scale, of a detachable sheet of musicusually employed by bands or orchestras.

Fig. 14 is a view of one of the Contact plates which is to be attachedto the music sheets to be engaged by the magnets.

Fig. 15 is a view of the improved device arranged upon the ordinarymusic rack or upper panel of a piano.

Fig. 16 is a section on the line 16-16 of Fig. 15.

When arranged for use upon a foldable standard as shown in Figs. 1, 2and 6, the improved device includes a central frame member 1() to whicha plurality of bars 11 are pivoted at 12 at their inner ends.

Slidable upon each of the bars 11 is a slotted extension bar 13, andpivotally coupled at 14 to the outer ends of the extension bars areother bars 15, the pivotally coupled bars permitting the folding of thedevice into small space when not in use, and the slotted extensionpermitting adjustment to adapt the device to sheets of various sizes.

Attached to the central frame member 10 is a bracket 16 to which asupporting rod 17 is rigidly coupled.

The improved device may be supported by a foldable stand of the usualconstruction and comprising telescoping members 18 and 19, pivotedfoldable legs 20 and pivoted foldable braces 21, the members 18 and 19being provided with clamp screws 22 to enable the stand to be held inadjusted position or folded into small space, when not in use, as willbe obvious.

Attached to the upper end of the member 10 is a small casing 23 in whicha bell crank lever device 24 is pivoted at 25. One arm of the member 24is extended into a toothed segment 26 engaging a gear pinion 27 on a rod28, the latter supported for rotation relative to the member 10.

Connected to one arm of the bell crank member 24 is a pull wire 29, andcoupled to the lower end of the pull wire is a coupling strip 30, andcoupled to the lower end of the stri is a pull chain 31.

. Suita ly supported on the floor, indicated at 32, is a pedal member 33to which the lower end of the chain 31 is attached, as shown in Fig. 1.

A SpringV 34 surrounds the rod-28, preferor more sheets to be turned,one of the `ably Within the :casing 23, land is attached' at one end tothe casing and at the other end to the rod, and exerts its' force tohold the rod yieldably in one psiti'on, and to return it to its firstposition when released. The rod 28 extends `above the lines of thecasing 23 and beloW the line of the lower members 11 and carries vleafturning arms I36u-at 'the extended ends.

djustably supported upon each of the turning 'arms 3G 'is a clip device37, the clip device 'being coupled to a vmagnet carrying f rod 38.Adjustably supportedon the rod 38 is va clip device 39fcarrying a magnet40, preferably ofthe horse-shoe form, as shown.

Support-ed upon one set of the bars r11,-

relatively near the-member 10 is a plate 41, and connected to thisplate, as by clips 42, are magnet members 43, preferably in horseshoeforni. Y I

Each sheetof music which is to be turned is provided at its outer edgewith a small imetal contact plate,`represented at`44, With which themagnet- 40l contacts Whenthe' turning arms 36 `and the coupling rod V38are in the position shown -in Figs. 1- and 6. Tlierslie'ets to belturned are also each vprovided with a small m'etal'co'ntact plate atthe inner edge, as shown at 45, in po- Y sitiontobelengaged Aby thelother lmagnets .43,-to hold'the backs or cover members'of' lthe music4sheet'srin vposition upon the'cen#y tralframe member 10, theYfo'ijeefof the 'magnets 43 being ksutcient to lhold the backs of thesheets from displacement by the force required to V'turna the looseleaf,or sheet,

y but-"Whichmay be removed and other sheets arranged'onV the holdingportion When anabnormal vforce isV applied.

,-lVhe'n the ordinary music sheet is ein- V Y ployed, `coinprising afront 46 and back 47 in one sheet' folded together and an intermediateloose leaf-48 between the front and back, as represented lin Fig. 12,the contactvplates 45 are applied to the intermediate sheet'48 only, the`front Yand back sheets 46 and 47 having portions cut out"as'i'epresented at 49 inFig. 12, to expose the contract 'membersVfor`"engagement by the magnets 43. VThen applie'dto the ordinary threesheet form, the Contact plates are attached to the-intern'iediate looseleaf only, asthisloose 'leaf'only is to be turned.-

The sheets employed for bands or orches-' tras'are` generally oftheloose leaf form, as represented'in Fig. '13,'Witheyelets 50 toenafble'them to'be detachably arrangedbetween covers, and in this casethe contact membersg44'only are employed, as the relatively stiff coversare'suflicient to hold the connected leaves in'place When the separateleaves are turned.

When the improved devicieisto be applied to a musical composition havingtwo from the central frame member 10, and the rear or inner edges of thesheetsr 48 are held against the member 10 by the magnets 43, hence 'whenthe turning rods 36 are actuated, the magnet 40 describes a. greaterhalf circle than the sheet 48 andits contact 4.4. By this arrangement asthe sheet 48 isfturned over by the act-ion of the rod 38 anditsmagnet40, the'magnet `Will 'be gradually Withdrawn from the contact 44and thus release the sheet Twhich ris thus folded over against thefront46, lea-ving the arms 36, rod 38 and magnet ,40'to be returned toformer position ready to' turn another sheet, if one or more sheetsarepto be turned. ln otherwvords, the magnet 40 Will be pulledk loosefrom 'the contact`44` as the turned 1n Figs. 15 and 16 the improveddevice is shown applied to the music support of a# piano, a portion ofthe Vfrontupper panel being represented at 51, and the lower Vfrontpanel at 52. When thus applied the rod 28 is supported upon therearqface "of 'the panel 51 and the bell cranlrmemberl24isi`ipf sheetapproaches its turned position. v

ioo y position to beengagedby thec'onta'ct members 45 of the sheets tobe turned. A mag net 57 for each of the contacts 56 is 'sup-` ported inthe panel 51 andthus energi-zes the contacts 45 .and 56 and holds`v'the'music sheets in position.

The panel 51 Vis provided WithgslotsjS through Which thefarms 36vprotrudefaiid operate, as shown. y

VThe improved device'is struction, can be inexpensively lmanufactured,and the partsadjustable to :adapt-itto sheets or leavesefvarious"sites,` and'to any required number of sheets or leaves. j

VThe preferred embodiment of the ii'ivention is disclosed in thedrawings?and,set

forth in thespeciiication, but it Will be. understood that modificationsWithin thescope of the .claimed invention'niayjb'e made in thecenstruction AWithout departing from the principle of the inventionor'sacrificingy any of its advantages. f Y l, o

Having thus described tl'ie'inventioinwliat is claimed as VneuT isz- Adevice of the class described comprissimple `in'V :con-

a magnet element movable with said turnmg arm 1n position to engage thearmature at the outer edge of the sheet, and means for actuating saidturning arm to cause the 1 magnet element to move the sheet toward openposition and be gradually Withdrawn from engagement with the armatureelement as the sheet approaches open position.

In testimony whereof, I afiix my signa- 20 ture hereto.
